[PATCH 0/6] arm64: dts: rockchip: misc. cleanups

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

Hi,

Here are a bunch of cleanups for rk3399 and rk3328.

  - Some dtc warnings were silenced, however a few still remain.
    Found those while making device tree overlays

  - Replaced some hardware specific device node names, such as dwc3
    and rk808, with generic names

  - Fixed MMC numbering for roc-rk3399-pc with mezzanine

The series is based on linux-next 2020-03-24. For some reason 2020-03-26
doesn't boot.

Please have a look.

Regards
ChenYu

[PATCH 1/6] arm64: dts: rockchip: rk3399-roc-pc: Fix MMC numbering for LED triggers

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

With SDIO now enabled, the numbering of the existing MMC host controllers
gets incremented by 1, as the SDIO host is the first one.

Increment the numbering of the MMC LED triggers to match.

[PATCH 2/6] arm64: dts: rockchip: rk3328: Replace RK805 PMIC node name with "pmic"

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

In some board device tree files, "rk805" was used for the RK805 PMIC's
node name. However the policy for device trees is that generic names
should be used.

Replace the "rk805" node name with the generic "pmic" name.

[PATCH 3/6] arm64: dts: rockchip: rk3328: drop non-existent gmac2phy pinmux options

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

When gmac2phy was added, a whole bunch of pinmux options were added.
Turns out some of these don't exist on the actual product, based on
the publicly available TRM.

Remove them.

[PATCH 4/6] arm64: dts: rockchip: rk3328: drop #address-cells, #size-cells from grf node

The device tree compiler gives the following warning:

    /syscon@ff100000: unnecessary #address-cells/#size-cells without
    "ranges" or child "reg" property

Since none of the grf node's direct child nodes have any reg properties,
remove the two properties from the grf node to silence the warning.

[PATCH 6/6] arm64: dts: rockchip: rk3399: Rename dwc3 device nodes to make dtc happy

[Chen-Yu Tsai]

From: Chen-Yu Tsai <wens@csie.org>

The device tree compiler complains that the dwc3 nodes have regs
properties but no matching unit addresses.

Add the unit addresses to the device node name. While at it, also rename
the nodes from "dwc3" to "usb", as guidelines require device nodes have
generic names.

dtc also complains about the usbdrd3 nodes not having regs properties
despite having unit addresses. What can we do about those?

Re: [PATCH 1/6] arm64: dts: rockchip: rk3399-roc-pc: Fix MMC numbering for LED triggers

[Johan Jonker]

Hi Chen-Yu Tsai,

The led node names need some changes.
'linux,default-trigger' value does not fit.

From leds-gpio.yaml:

patternProperties:
  # The first form is preferred, but fall back to just 'led' anywhere in the
  # node name to at least catch some child nodes.
  "(^led-[0-9a-f]$|led)":
    type: object

Rename led nodenames to 'led-0' form

Also include all mail lists found with:
./scripts/get_maintainer.pl --nogit-fallback --nogit

devicetree@vger.kernel.org

If you like change the rest of dts with leds as well...

Hi Chen-Yu Tsai,

The Documentation/ portion of the patch should come in the series before
the code implementing the binding.

If you like, could you convert the binding as well and fix the example?

Documentation/devicetree/bindings/pinctrl/pinctrl-rk805.txt

The name is not part of the binding.

I can send an extra patch to fix the example.

Maybe we should just get rid of linux,default-trigger then?

Heiko?

In this particular case, I'd say it's probably time to reevaluate the 
rather out-of-date binding. The apparent intent of the 
"linux,default-trigger" property seems to be to describe any trigger 
supported by Linux, so either the binding wants to be kept in sync with 
all the triggers Linux actually supports, or perhaps it should just be 
redefined as a free-form string. FWIW I'd be slightly inclined towards 
the latter, since the schema validator can't know whether the given 
trigger actually corresponds to the correct thing for whatever the LED 
is physically labelled on the board/case, nor whether the version(s) of 
Linux that people intend to use actually support that trigger (since it 
doesn't have to be the version contemporary with the schema definition), 
so strict validation of this particular property seems to be of limited 
value.

I agree. It is possible for LED class drivers to register their private
triggers, so generic bindings cannot use predefined set for validation.

I think that Rob just blindly converted common.txt to yaml and I acked
that but didn't envisage the implications for validation.
All in all, even that list in common.txt didn't include all existing
generic LED triggers.

It is enough to keep it in sync with all the triggers we actually use :-).

But freeform seems acceptable, too.

This label probably should be "mmc1:red:activity" or something like that.

And this label should be changed, too.

I'd say free form is easier to manage. Being in the list of valid triggers
doesn't mean the kernel actually has support for it enabled.

Is changing this after it has been in some kernel releases OK? Wouldn't
it be considered a break of sysfs ABI?

Also, is there some guideline on how to name the labels? For sunxi we've
been doing "${vendor}:${color}:${function}" since forever.

As far as I can tell, the hardware vendor [1] has no specific uses for
these two (red and yellow) LEDs designed in. And their GPIO lines are
simply labeled "DIY" (for the red one) and "YELLOW". So I'm not sure
if putting "our" interpretations and the default-trigger into the
label is wise.

For reference, the green one has its GPIO line labeled "WORK", and their
intention from [1] is to have it as some sort of power / activity indicator.
Hence it is named / labeled "work".

As for the node names, I think we can keep it as is for now. It's not
the preferred form, but there's really no need to change it either.
And some overlay or script might actually expect that name.

I've applied patches 2-6 as fix for 5.7.
The discussion on patch1 somehow stopped on monday, so feel
free to resubmit that one separately once everybody is happy
